Abstract (en)
A remotely positioned rotary operator handle for cooperating with a circuit breaker (20) with a linearly movable handle (22). A housing (26) is mounted over the circuit breaker handle (22). Within the housing a slide carrying a rack engages the circuit breaker handle which further engages a pinion gear sector mounted on a rotatable shaft. The rotatable shaft extends from the housing (26) and has positioned thereon a motion translating device which translates between rotational motion and linear motion. The rotary handle (124) extends from a housing which is flange mounted on a cabinet (126) in which the circuit breaker is disposed. A corresponding motion translating device (104) is attached to the flange mounted rotary handle (124) which is in turn connected to the motion translating device (102) attached to the rotatable shaft. The connection between the motion translators comprises a linearly moving link. The rotary handle has an extendable hasp which comprises part of the connection between the rotatory handle and the motion translating device. The hasp provides a means for the handle to be locked in the circuit breaker off position. The hasp has a foot (224) which fixedly engages the rotary handle housing when in the extended position thereby preventing the rotation of the rotary operator handle. The hasp further has an aperture which accepts the shackle of a lock for locking the hasp in the extended position. <IMAGE>
